Webb12 apr. 2024 · Muscles are composed of millions of individual muscle fibers that contract and relax to generate movement. These fibers differ in their structure and function, and are classified into three main types: slow-twitch (type I), fast-twitch oxidative-glycolytic (type IIa), and fast-twitch glycolytic (type IIb/x).

Webb16 juni 2024 · Each muscle fiber is an individual muscle cell and may be anywhere from 1 mm to 4 cm in length. When we choose to contract a muscle fiber—for instance we contract our bicep to bend our arm upwards—a signal is sent from our brain via the spinal cord to the muscle. This signals the muscle fibers to contract.
